1 General DescriptionBL-8188-EU1 productAccord with FCC CE andis 150 wireless USB adapter which has lower power consumption, high linearity output power, accords with IEEE802.11B/G/N, and supports IEEE802.11i safety protocol, along with IEEE 802.11e standard service quality. It connects with other wireless device which accorded with these standards together, supports the new data encryption on 64/128 bit WEP and safety mechanism on WPA-PSK/WPA2-PSK, WPA/WPA2.Its wireless transmitting rate rises 150M, equivalent to 10 times of common 11b product. The inner AI high gain ceramics antenna adapts different kinds of work environment. It’s easy and convenient to link to wireless network for the users using desktop, laptop and other device that needs connect to wireless network.2 The range of applyingMID, networking camera, STB GPS, E-book, Hard disk player, Network Radios, PSP, etc, the device which need be supported by wireless networking.3 FeaturesFeatureImplementationPower supplyVCC_3.3V+-0.2VClock source40MHzTemperature rangeWorktemperature:-20ºC---70ºC
